Description

Tubular configured joint

Technical field

The present invention relates to the field of the tubular configured joint for connecting fluid line or pipeline section (such as, for the fuel hose of Motor Vehicle).

More specifically, the present invention relates to a kind of tubular configured joint, comprising: female connector, the male connector being provided with annular collar is designed to axially be inserted in this female connector; And connecting element, it extends in a lateral direction in female connector, and be designed to when male connector is inserted in female connector by with described axle collar mechanical interference and towards the outer radial resiliently deformable of female connector, and, as the reaction to this elastomeric radial, himself moves towards the inside of female connector in a lateral direction described.

Background technique

Such tubular configured joint for hose is known, particularly from patent documentation US2012/0326435.

In this known tubular configured joint, connecting element is configured for the holding member when male connector is driven fully in female connector, male connector being locked in appropriate location, particularly by breech lock, this axle collar rear being latched in male connector is with the mode horizontal expansion in female connector it axially locked.

Connection or holding member are also provided with two pins, described pin is spaced apart from each other, and as same U-shaped clip, and extends in a lateral direction in female connector inside, each pin has the axial opposing side (towards face, facingface) of interfering with the axle collar of male connector.

First connecting element is positioned in female connector with preassembly high position, in this preassembly high position, the web that U-shaped portion is divided is projected into female connector outside, and two of connecting element pins extend to substantially in the front of the axle collar of described male connector on the either side in male connector (if think that the front of the axle collar corresponds to the axle collar be positioned at further downstream axial opposing side along axis in an insertion direction, male connector is inserted in female connector in an insertion direction).

When male connector is pushed axially in female connector, so interfere to opposing side with the front axle of the pin of connecting element before the axle collar of male connector, described front axle tilts to opposing side relative to axial direction and relative to horizontal direction.Result is, make the pin of connecting element as radial elastic is moved apart to the reaction of the thrust on opposing side to being axially applied to inclination front axle, and make connecting element as to be laterally applied to described inclination front axle to the reaction of the thrust on opposing side in female connector transverse shifting.While radial elastic is moved apart, resilient prongs savings reset energy.During the transverse shifting of connecting element, the ultimate range that resilient prongs is moved apart corresponds to the diameter of the axle collar.

While connecting element is moved down in female connector, pin is moved apart on the axle collar, is moved apart at utmost, that is, the diameter of the axle collar until pin reaches it.Like this, once they have exceeded this diameter, and by means of the elastic movement separately energy of savings, pin has utilized and has extended in a lateral direction and continue the thrust component of the inner transverse movement making connecting element towards female connector momently and reset.

Thus obtain a kind of joint from being dynamically connected.

Connecting element in the tubular configured joint that this is known further comprises fixed frame, this fixed frame in female connector laterally and extend with being parallel to the pin of connecting element, further, there is the elastic tongue piece tilting to extend relative to the axial direction of female connector bottom it.

This tongue piece is arranged in such a way, that is, when male connector is pushed axially in female connector, male connector pushing tongue piece, makes it move axially relative to bottom it.Result is, elastic tongue piece stores energy by compressing, and, while connecting element transverse shifting, when the resilient prongs of connecting element exceedes the diameter of the axle collar, tongue piece is released and produces thrust on connecting element, and this thrust is tending towards its inside towards female connector is moved in a lateral direction.

So connecting element is in it keep lower position, at this maintenance lower position, breech lock and then prevent male connector from moving axially in female connector.At this lower position, connecting element is rendered as and is almost fully retracted in female connector.Tongue piece thus pushing of connecting element can be made to extend in female connector after exceed the diameter of the axle collar of male connector during the transverse shifting of connecting element.

Regrettably, this known tubular configured joint has shortcoming.

First, it needs multiple separate parts interact with each other, to realize being kept by male connector or being locked in female connector and by the automatic movement of connecting element towards the inside of female connector.

These different parts need to carry out complicated driving between which and coordinate.They also add the cost manufacturing this tubular configured joint.Tubular configured joint also has the body being with many through holes, and described through hole makes this tubular configured joint not too firm.

In addition, the stroke of connecting element after exceeding the axle collar depends on the amplitude that tongue piece is out of shape, and in practice, due to the miniaturization of parts, the trip is relatively short.

As a result, the alternate position spike between the preassembly high position of connecting element and lower position is very little, and thus perceive this alternate position spike by estimating or touch poor difficulty.

Summary of the invention

Therefore, the object of the invention is to reduce the shortcoming pointed out above.

For this reason, the invention provides a kind of tubular configured joint, comprising: female connector, the male connector being provided with annular collar is designed to axially be inserted in this female connector, and connecting element, it extends in a lateral direction in female connector, and be designed to when male connector is inserted in female connector by with described axle collar mechanical interference and towards the outer radial resiliently deformable of female connector, and, as the reaction to this elastomeric radial, himself moves towards the inside of female connector in a lateral direction described, the feature of described tubular configured joint is, described connecting element and described female connector are also designed so that after the elastomeric radial of the axle collar for male connector to connecting element reacts, they bear against each other in protuberance mode, pass through elastic reset, protuberance applies pressure on guiding surface, so that described in a lateral direction towards the thrust of the movement of the described connecting element of inside generation expansion of female connector.

Therefore, basic thought of the present invention is, enables the energy discharged when its elastic reset by connecting element effectively change into thrust, this thrust of control and guidance in a lateral direction of the movement in the inside towards female connector of connecting element.Particularly, inclined-plane can be designed as, and can extend the mode of connecting element movement in a lateral direction, extends beyond the axle collar in a lateral direction.

Utilize this structure of the present invention, a connecting element mobile longer stroke in a lateral direction can be made, thus connecting element can be positioned at the pre-assembled position of the height be highly greater than in above-mentioned known tubes straight coupling, and, in addition, connecting element can also be forced to enter into female connector through a larger distance.

Result is, utilize this structure of the present invention, the location of connecting element between its pre-assembled position and its lower position can be made to have difference, and this difference is enough large, to be configured for vision or to check that male connector is connected to the reliable indicator of female connector completely by touching.In addition, utilize this structure of the present invention, can obtain the covering of connecting element on the axle collar, it is enough to ensure good mechanical strength.

In addition, can keep relative closure female connector body (that is, not having anything to pass its opening) in realize structure of the present invention, thus can decreasing pollution source (such as, be deposited on the dust of female connector inside) impact, and increase the steadiness of body.

Embodiment

As can be seen in Figure 1, tubular configured joint of the present invention comprises cloudy tubular tip parts (female connector) 2, in this example, female connector is two-part, is included in axial direction A and extends and be provided with the tubular body 3 of axially open 4 and be suitable for the ring 5 of axial engagement in main body 3 by being assembled in opening 4.

Be understandable that, the present invention is extended to female end parts that are that comprise one or that form a Unitarily molded part.

In tubular configured joint 1, positive connecting tubular end pieces (male connector) 6 is arranged for and is axially inserted in female connector, and in this example, is inserted in its ring 5.

Male connector 6 is the form of elongate cylindrical tube, and has the annular collar 7 around its circumference, and the diameter of annular collar 7 is slightly less than the internal diameter of ring 5.As also found out in FIG, the main body of female connector is inner hollow, and have radial opening 8 at top, form a kind of slideway, connecting element 9 can be inserted laterally in this slideway, and described connecting element can slide in this slideway.

In this example, connecting element 9 is for having the form of the U-shaped clip of two resilient prongs 10, and described pin is spaced apart from each other and links together at web 11 place of U-shaped.

Two pins 10 are that forming profiles is made, and make them form a kind of supporting leg (runner, slide part) that can slide in the groove of the slideway limited by radial opening 8.

Connecting element also comprises breech lock 12, and this breech lock is designed to when male connector is driven fully in female connector 2 to keep male connector and the mode locked it in axial direction A is positioned at the axle collar rear of male connector 6.

The pin of connecting element 9 is also set to, connecting element self is moved on horizontal direction T by means of the inside of thrust towards female connector 2, this thrust is produced by the reaction of the elastomeric radial to pin, and described elastomeric radial occurs when being pushed in female connector by male connector.

More specifically, each pin 10 of connecting element 9 has the axial opposing side 10A when described male connector is bonded in female connector 2 in the face of the axle collar 7 of male connector 6.

Position below the midplane that it is positioned at the axially open 4 of female connector 2, the axial opposing side 10A of each pin 10 has inclined surface 13, when connecting element 9 is in this preassembly high position of female connector 2 inside, this inclined surface is used for when described male connector is pushed in female connector 2 and the axle collar 7 of male connector 6 is interfered.

When connecting element is inserted in female connector, surface 13 both also tilted to extend relative to horizontal direction T relative to axial direction A, to produce the described thrust pointing to horizontal direction T.

In addition, according to the present invention, and, such as, on the axial opposing side 10A of each pin 10 of connecting element (and, in this example, the top at inclined surface 13), be provided with at the outstanding protuberance 14 of axial direction A.

In this example, the cross side of the circumferential exterior surface of ring 5 is formed with two guiding surfaces 15 relative to each other tilted.This two guiding surfaces 15 are in the face of a gap radial groove 8A, and described gap radial groove is visible in FIG and be arranged in the ring-type peripheral surface of female connector 2.These radial grooves leave the idle space for making the pin of connecting element move out in female connector inner radial, can also be provided with the transverse latch engaged with the top of radial groove, deviate from female connector to prevent connecting element for described pin.Under the prerequisite do not limited the scope of the invention, also on the non-flexible position of connecting element, breech lock (not shown) can be set in the mode be bonded in the radial groove of female connector.

These two inclined ramp 15 start from the position under the midplane of the opening 4 being starkly lower than female connector, and towards female connector sidepiece (with radial opening 8 diametrically) radial direction T on extend toward each other.In this example, these two guiding surfaces 15 be straight line and with axle collar axialy offset, and they form a kind of V-arrangement together, when observing in the axial direction, ride the axle collar (in other words, axle collar assembling forming V-shape) of male connector.

Protuberance 14 and guiding surface 15 are configured to, to make when connecting element 9 is inserted in female connector 2 and when it exceed male connector 6 the axle collar 7 (, from the front of the axle collar 7 to rear) time, so pin is spaced apart from each other completely, each protuberance 14 on corresponding pin is bearing on corresponding guiding surface 15, and the supporting of pin on the side face of the axle collar 7 in male connector is tending towards reducing.Supporting on axle collar side face is tending towards being substituted by the supporting on inclined-plane.

In fig. 2 a, male connector 6 is partially inserted in female connector 2.

Connecting element 9 is in preassembly high position in female connector 2.

The pin 10 of connecting element 9 is positioned at the front of the axle collar 7 of male connector.

Protuberance 14 on each pin 10 abuts against the top 16 of a lead-in chamfered 15, and this is visible by the radial groove 8A in female connector.

In figure 2b, male connector 6 is driven fully in female connector 2.

Connecting element 9 is in this maintenance and locking lower position in female connector.The breech lock 12 of connecting element 9 is positioned at the axle collar 7 rear of male connector, prevents any in female connector 2 of male connector 6 from moving axially thus.

So the protuberance 14 on each pin is locked in the recess 15a at the bottom place of inclined surface 15, thus prevents by means of only pulling on connecting element 9 and make connecting element remove from female connector, as shown in Figure 6.But, can arranging like this, from the recess inclined-plane, after disengaging (such as, by using pointed), connecting element can be made to remove from female connector by intentional at protuberance 14.

As shown in Figure 2 b, when connecting element is in lower position, the top (that is, the web of U-shaped clip) of connecting element 9 flushes with the outer surface (being top surface in this example) of female connector.

When connecting element is in preassembly high position, the top of connecting element 9 be projected into relative to female connector outer surface of cupular part such as roughly at 4 millimeters (mm) to the degree of 5mm scope, be enough to enable operator by visual examination or by touching lower position and the preassembly high position of distinguishing connecting element for certain.

The driving of connecting element when himself moves in female connector has been shown in Fig. 3 a to 5b.

In Fig. 3 a and Fig. 3 b, connecting element 9 is in preassembly high position.Male connector 6 to be partially inserted in female connector 2 and to be in pre-assembled position.

The pin 10 of connecting element 9 is positioned at the front of the axle collar 7 of male connector.

Specifically can find out, inclined surface 10A (inclined surface 10A is arranged in the rear of pin 10 in the drawings) on each pin 10 is arranged on the curved part of pin 10, this curved part at the downward-extension of the midplane M of the axially open of female connector 2, and in the axial direction with the axle collar 7 mechanical interference of male connector 6.

In this case, each protuberance 14 abuts against edge 16 in the end on respective guide inclined-plane 15.This layout can prevent connecting element to be pushed in female connector unintentionally when male connector is not present in female connector.

In figs. 4 a and 4b, male connector 6 is pushed in female connector further a little, and the axle collar 7 applies axial pressure on the inclined surface 10A of the pin 10 of connecting element 9.

Once protuberance 14 is disengaged with the edge on inclined-plane 15, this end thrust makes pin 10 move radially separately, as shown by arrow E, meanwhile, causes in a lateral direction towards the translational motion of the inside of female connector, as shown by arrow D.

Can find out in these figures, once it is disengaged with the edge 16 of inclined surface 15, each protuberance 14 allows connecting element to move, as shown by arrow D.So each protuberance 14 can be configured to towards inclined-plane 15.

In figs. 5 a and 5b, male connector 6 is driven fully in female connector 2.

By moving laterally in female connector, pin 10 through male connector the axle collar 7 " under ", that is, they cross the midplane of the axle collar 7 in the directiond, and by moving towards each other elastic reset, as indicated by arrowr.

So protuberance 14 applies pressure on inclined-plane 15, this pressure is converted into thrust component, as shown by arrow D, thus makes connecting element 9 self continue its movement towards female connector inside, until protuberance arrives the bottom on inclined-plane 15.Be understandable that, each protuberance 14 moves, until it is applied to the pressure vanishing on described inclined-plane by slipping over inclined surface 15.So connecting element 9 arrives it at the maintenance of female connector inside and locking lower position.

In an embodiment of the present invention as shown in figure 7, can arrange rib 17 or projection on the surface on each inclined-plane 15, described rib or projection are arranged in such a way, namely, the protuberance 14 crossing described rib or projection 17 produces click, arrives the audible indicator of its end of travel as connecting element.These ribs are also designed to, and allow locking member to be only moved down into lower position, and prevent it under influence of vibration, going back up to pre-assembled position.Still it is possible that make connecting element move back to pre-assembled position by applying the tractive force that is enough to make pin be out of shape.

In tubular configured joint 1 of the present invention, also can be provided for checking that male connector is driven fully into the visual detector in female connector, such indicator is the form of mark, such as, described label placement is in the lower end on each inclined-plane, retain and locking lower position once connecting element arrives it, this mark is just covered by protuberance.Can also provide the mark be arranged on connecting element, once connecting element is inserted in female connector, this mark is just capped.

Connecting element in the joint that is dynamically connected of the present invention can be suitable for the male connector of different profile or different-diameter and be suitable for the axle collar of different radii.

Tubular configured joint 1 of the present invention is made up of the different parts of minority, and all parts can be made up of plastic materials, such as, pass through injection moulding.

In the variant embodiment of shown in Fig. 8 of the present invention, can arrange a kind of clip 18 of staple shape in tubular configured joint, this clip checks the indicator whether joint has correctly assembled with serving as two benches.Once male connector 6 is properly inserted in female connector, this indicator clip 18 is outstanding from joint, namely it is in high position, as shown in phantom in Figure 9, and makes operator visually or can pass through to touch the first inspection carried out joint and whether correctly assemble.

Then second inspection is undertaken by the second operator, and the second operator also determines that this indicator clip 18 is in extrusion position and it is manually pushed in joint, until it is no longer outstanding, namely until it is in lower position, as shown in the solid line in Fig. 9 and Figure 10.

This two benches inspection makes it possible to determine that joint correctly assembles, thus the assembly error on restricted group wiring.

In this example, indicator clip is the form of the staple formed by two pins 19, and these two pins are flexible and parallel substantially, as visible in Fig. 8 and Figure 10.

The pin 19 of indicator clip 18 is designed to, before insertion male connector, the horizontal direction T shown in Fig. 8 is inserted in connecting element 9 for this purpose and in the groove 20 provided.

Once insert, the compliant pin of indicator clip 18 just applies pressure on the Internal periphery of female connector 2, prevents indicator clip 18 from being removed unintentionally.

Also be understandable that, while male connector 6 is inserted in female connector 2, connecting element 9 moves laterally in female connector 2, so that lock male connector 6, and indicator clip 18 is given prominence to from this joint, remains in high position.Once male connector is properly inserted into, the end of the pin 19 of indicator clip just stands upright on male connector 6, thus prevents indicator clip 18 to be moved down into lower position when not applying extra-push model.

It should be noted that the mechanism that the mechanism that connecting element 9 moves down does not move down with indicator clip 18 interacts, because indicator clip is manually pushed into lower position by operator.
